Let’s remember, this survey is currently preliminary. That means further inspection and discussion could lead to an EF-5 rating.
That said, if this doesn’t end up there in the coming weeks, I agree with the sentiment that has been expressed in this thread. Basically, there’s almost no areas out there that have structures built up to the standard that would enable an EF-5 rating, and contextual evidence beyond that is just not seen as reliable enough to give a rating beyond that, even if it should be IMHO.
